Abstract

The main objective of this project is to perform torque analysis for two heavy duty truck engines by determining stiffness. While finite element analysis is used for determining the stiffness, 1-D modeling using AMEsim utilized for understanding the torque variation. This work is necessitated to understand the variation of measured torque of heavy-duty truck engines, using a virtual torque sensor developed by Dr. Ghantasala’s group. Today, companies are always looking to improve fuel efficiency and overall engine performance. The sensor increases fuel and engine efficiency on heavy-duty trucks by collecting and providing more accurate torque measurements from the flywheel of the vehicle. Two heavy duty truck engines, CAT C-15 (diesel) and Cummins ISX12G (compressed natural gas) crankshafts, are chosen for this purpose. Stiffness values were calculated from FEA analysis using ANSYS and SolidWorks software and are compared with the values obtained through simple analytical calculations. We explored MATLAB as well as AMEsim for 1-D modelling of torque from these engines and this report provides our findings in detail.
